Robert Boyle Flask

  1. May 20, 2015 #1
    Hello everybody! I am new here and have not looked around much on the forum for an answer to my question, so sorry if this should be obvious to me but:
    I want to create a model of the Robert Boyle ever flowing flask for my class.

    For those of you who do not know what this is, it is basically a funnel with a hose that goes from the bottom, around, and back into the top of the funnel to replenish the supply... hence... ever flowing.

    Of all the videos on Youtube i have never seen one work well but i have recently come up with an idea. What if you put your mouth on the end of the hose and suck the water/soda/beer through until it reaches the end and flows into the funnel??? Would this be a type of venturi and would it work? I am planning on tying this but would like an answer is someone has one.

    Thanks for any suggestions or information you guys can give me!!!

    You do know Boyle's flask is a perpetual machine, so it can't work, right?

    I know that, but it seems like there would there would be more potential helping it start, instead of letting the liquid simply balance itself. I know i am grasping at straws but it seems so entertaining!
